The Filter parameter requires an expression that specifies the property value criteria for the messages that you want to resume. The expression includes a property name followed by a comparison operator and value. The following message properties are valid criteria for the Filter parameter:

DateReceived The date that the message was received.

ExpirationTime The time that a message will expire.

FromAddress The SMTP address of the sender of a message. This value is taken from MAIL FROM in the message envelope.

Identity An integer that represents a particular message, and an optional server and queue identity.

InternetMessageId The value of the Message-ID message header field located in the message header. This property is expressed as a GUID followed by the SMTP address of the sending server, for example: 67D7543D6103DC4FBEBA6BC7205DACABA61231@exchange.contoso.com.

LastError A text string of the last error recorded for a message.

MessageSourceName A text string of the name of the component that submitted this message to the queue.

Queue The identity of the queue that holds the message. Enter the queue identity in the form of Server\destination, where destination is a remote domain, Mailbox server, or persistent queue name.

RetryCount The number of times that delivery of a message to a destination was tried.

SCL The spam confidence level (SCL) of the message. Valid SCL entries are the integers 0 through 9. An empty SCL property value indicates that the message hasn't been processed by the Content Filter agent.

Size The size of a message.

SourceIP The IP address of the external server that submitted the message to the Exchange organization.

Subject A text string that represents the e-mail subject. The value is taken from the Subject header field.

You can specify multiple filter criteria by using the and comparison operator. Property values that aren't expressed as a single integer must be enclosed in quotation marks (").

Identity

Required

Microsoft.Exchange.Data.QueueViewer.MessageIdentity

The Identity parameter specifies the MessageIdentity integer. This is an integer that represents a particular message, and an optional server and queue identity. The syntax for this parameter is as follows:

Server\QueueIdentity\MessageIdentity

QueueIdentity\MessageIdentity

Server\*\MessageIdentity

MessageIdentity

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

Server

Optional

Microsoft.Exchange.Configuration.Tasks.ServerIdParameter

The Server parameter specifies the name of the server to connect to by using the remote procedure call (RPC) that contains the queues that hold the messages that you want to resume. Enter the Server parameter as a host name or a fully qualified domain name (FQDN). If this parameter isn't used, the local server is queried.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

A message being sent to multiple recipients might be located in multiple queues. If you specify an Identity parameter, the message is resumed in a single queue if that identity matches only a single message. If the identity matches more than one message, you receive an error. To resume a message in more than one queue in a single operation, you must use the Filter parameter.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Queues" entry in the Transport Permissions topic.
